Good Things Come In Small Packages

Working on a one-pipe system with two mains and a counter-flow branch. Going through the darkness to find the end of the counterflow main in search of a vent I found instead a coin vent/bleeder. That was a first. I can see why perhaps they thought about using it (even though it could never work): No headroom. Just a few inches before the lath, which probably had plaster on it when this "vent" was installed.

    Not a particularly long branch, so the 1/4" taping would suffice and there'd be no need to drag out the 700. Still, not much headroom! The lath could be cut away, but who enjoys that mess?

    And then I thought of Peter and his new Vari-Vent. The little vent that could. Big vent, small package. Thank-you Peter! (though I would consider putting a tiny hex key / wrench in the box for the adjustment if I owned Barnes & Jones :).

    That's probably a hygroscopic vent, which some attempt to use on steam- we take them off and put on real vents.
